I don't know whats a bug and whats a feature anymore;
When you fill a lure plant over capacity it appears the excess is converted into leafy meat. We still haven't tested if any or all digested items are converted to leafy meat but we do know if its over capacity you get a ton of leafy meat.
Steps to Reproduce
1. Plant a Fleshy Bulb 2. Wait for eyes to spawn 3. Give it 15+ stacks of items to eat 4. Destroy the bulb and collect the meat
